BULLION-FRINGE LOOM.

Application filed November 30, 1923. Serial No. 677,698.

To all whom t my concern:

Be it known that we, CARL C. WALLISER and ROBERT E. WALLIsER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and -useful Improvements in Bullion-Fringe Looms, of which the following is a specification.-

One object of our invention is to improve the construction of bullion fringe looms of the type which are capable of simultaneously producing a number of widths of fringe.

Another and specific object is to so coni struct and arrange parts of a loom that'a greater number of widths of fringe can be made in a given space than was heretofore possible, thus increasing the production and enabling a reater amount of fringe to be made on a oom of given width than was heretofore possible.

A further object is to provide improv'ed driving and actuating means for looms of the above type.

A still further object is to provide a loom of the above mentioned type in which the parts will be strong and durable and will not easily get out of working order.

Another object is to arrange and construct the parts of our invention so as to allow ready access thereto and so as not to interfere with the visionor pro er attention of the operator to the work W en the loom is in operation. Y

These objects and other advantageous ends which will be set forth hereinafter we attain in the following manner reference being had to the accompanying drawings in which- Figure 1 is an end elevation of a bullion fringe loom having our invention thereon,

(Bigure 8 1s a top plan view of Figure 7, an i 'Figure 9 is a fragmentary elevation showing certain `of the features illustrated in Figures 7 and 8.

Referring to the drawingsl and particularly to Figures 1 to 6 inclusive, 10 represents the frame of a bullion fringe loom of a well known construction; the same including an overhead support 11 with a bracket structure 12 upon which a lay 13 is pivoted. The lay 13 has reeds 14 through which pass the warp threads of the various fringes; the warp threads for each width of fringe being arranged in groups 15 as clearly shown in Flgure 2 of the drawings. These warp threads can be actuated, to produce the sheds, by heddle frames` 16 in the usual manner, the operating means for the heddle frames not being illustrated in the drawings. The lay 13 can be moved to produce the beat-up, by any suitable means and on the drawings we have illustrated a connecting rod 17 which is actuated by a crank pin 18 on a wheel 19 which is secured to the cam.

shaft 20. y

The parts thus far specifically described do not 1n themselves constitute a part of our invention since they are well known in the art of producing fringe.

In carrying out or invention we provide a number of brackets 21 preferably of a structure clearly shown in Figures 3 and 4 of the drawings and since these brackets 21 are all of substantially the same construction kwe will describe but one in detail.

Each of said brackets has' an offset portion 22 adapted to be secured by bolts or other means to the under surface of the breast beam 23. From the part 22 projects a part 24 which has `an eyelet or bored projection 25 which forms a bearing for a horizontal shaft 26. Each bracket 21 has an upwardly extending part 27 with an overhanging lug 28 which is spaced above thepart 24; said lug being bored to provide a bearing for a stud shaft 29, the part 24 below the lug 28 also providing a step bearing for the stud shaft 29. l

The shaft 26 has bevel gears 30 Secured l thereto which mesh with bevel pinions 31 which are secured to the various stud shafts 29 of the brackets 21. The upper parts of the portions 27 of the brackets 21 have bear* ings for twister spindles 32 said bearings having removable portions 33 to allow the twister spindles 32 to be easily inserted or removed. These twister spindles have portions 34 of larger diameter than the portions within the confines of the bearings to prevent lengthwise movement of the twister spindles in one direction. Each Atwlster spindle has a toothed gear wheel 35l secured to its opposite end so that the bearlng for each twister spindle is confined between the portion 34 of the twister spindle and the gear wheel 35. The gear wheels 35 mesh respectively with gear wheels 36 on a horizontal shaft 37 said shaft being supported by a number of arms 38 which are secured to the breast beam 23 as clearly shown in 'Figure 2.\

Weft inserting members 39 have angularly disposed portions 40 and 41, the por- I tions 40 being secured to the upper ends of respective stud shafts29. The members 39 are preferably made of cast'metal wlth the portions 41 at a slightly lower level than the Vportions 40. The portions 41 have angularly extending fingers 42 which are grooved at their free ends as shown at 43, said fingers 'preferably extending substantially parallel with the portions 40 as clearly shown in Figure 3.

Each twister spindle 32 has a pin 44 projecting outwardly from the side thereof and said pins are preferably made of spring steel wire. l

It will be noted that the brackets 21 are spaced apart within the width of the loom and that each of said brackets forms a support for one of the weft inserting members 39 and one of the twister spindles 32 with the exception that one of the end brackets, which is specilically numbered 21a, has no twister spindle thereon and that the bracket at the opposite end of the loom, specifically numbered 2lb, has no weft inserting member thereon. Thus it will be understood that each of the intermediate brackets 21 support a weft inserting member and a twister spindle. The reason for this arrangement will be rendered obvious by the following deserption.

The shaft 26 has alever 45 secured thereto and said lever 45 is connected by a link rod 46 with a bar 47 which is pivotally mounted at 48 on a standard 49. The bar 47 hasv a pin 50 which projects into a cam groove 51 on a cam 52 which is securedto the shaft 20, the arrangement, being such that for every revolution of the shaft 20 the bar 47 will receive one complete oscillation and consequently the shaft 26 will receive one complete oscillation causing the weft inserting members to oscillate on the axes of the stud shafts 29. v

The shaft 37 at one end has a bearing in a bracket 53,'said shaft at its outer end having a bevel gear 54 which meshes with a bevel gear 55 secured to a shaft 56 adjacent one end of the loom. The shaft 56 extends at an incline, the upper end thereof being mounted in ya bearing 57. The bearing 57 has a projecting portion 58 which extends through a slot 59 in the bracket 53 and is adjustably secured to the bracket 53 by means of the nut 60. The lower end portion of the shaft 56 is mounted in a bearing 57 which is adjustably secured to a bracket 61, said bracket having a slot 62 through which a portion of the bearing 57 projects and said bearing is secured by a nut 63. A toothed bevel gear pinion 64 is secured to the shaft 56 and, as clearly shown in Figure 5, said gear pinion has a dwell portion 65 which as illustrated is of. greater width than any of the teeth of said pinion. The pinion 64 is adapted to co-act with a gear wheel 66 secured to the cam shaft 20. In the present instance the gear wheel 66 has beveled gear teeth 67 and a plain beveled surface 68 between said gear teeth 67, the teeth 67 projecting beyond the plane of the surface 68 as shown in Figure 5. The surface 68 terminates at each end in an inwardly curved portion 69 which intersects the space 70 ata position slightly outward from the inner end 71 of said space 70. As illustrated there are ten teeth on the pinion 64 in addition to the dwell portion 65 and there are eleven teethon the gear wheel 66, the opposite sides of the dwell portion 65 making up the additional tooth of the pinion 64. The outermost surface of the dwell portion 65 can register with the surface 68 and when said latter surface is opposite said dwell portion 65 said surface 68 can smoothly slide over the outer surface of the dwell portion 65 during which action the pinion 64 cannot rotate. However, when one of the end teeth 67 engages one side of the dwell portion 65 the adjacent curved part 69 will allow the pinion 64 to rotate by providing clearance and consequently allow the adjacent tooth of the pinion' 64 to enter the space 70. It will thus be noted that with the construction illustrated and above described, in every complete revolution of the wheel 66 the shaft 56 will' receive one complete rotation and then the part 65 will move into close position in respect to the surface 68 thereby causing the shaft 56 to stop rotating at a definite, predetermined position which is especially desirable as will be better comprehended from the following description.

In Figure 2, seven widths of fringe are illustrated which are respectively/shown at A, B, C, D, E, F and G,each width of frmge being loca-ted between two of the brackets 21, the unwoven portions of the warps of the respective fringes being in line wlth the fringe headings; said warps being actuated to produce the sheds as previously stated.

The various weft threads 72v which are used to interweave with the warp to produce the headings and also to produce the twisted will move a loop of the weft thread to the pin of a twister spindle on an adjacent bracket and-by employing only a single supporting bracket between each two series of warp threads or fringes, the fringes can be positioned close together allowing a greater number of fringes to be woven in a given space. By spacing the pins 44 outward from their bearings 33, space is provided between the bearings and the pins for the widths of the fingers 42 of the weft inserting members 39 as clearly shown in Figure 6. The tops of the pins 44, when the twister spindles 32 are at rest, are slightly above the plane of the weft loops when they are passing over the twister spindles as shown in Figure 6. Thus after the weft threads are pushed over the pins the thread will assume a position in front-of and below the tops of the pins and, when the twister spindles are rotated, the pins 44 will serve to twist the loops of weft into twisted strands of bullion. The timing of the various parts is such that after the fingers have placed loops of the wefts around the pins 44 the fingers will .be retracted to their normal positions as shown in Figures 2, 3 and 4 and the twister s indles will be rotate-d the number of revolutions prescribed by the pinion 64 and gear wheel 66; there being n0 possibility of the twister spindles overrunning. j

After the strands have been twisted they are knocked off' the Apins 44 by mechanism now to be described: shaft 74 is supported by bearings 75 depending from the brackets 2l. This shaft 74 has blocks 76 adjustably secured thereon. The blocks 76 have knockoff arms 77 secured thereto, said blocks having holes 78 in vwhich the knock-ofi' 'levers are secured by set screws 79. A lever 80 has one end secured to the shaft 74and its other end pivotally connected by a link 81 to a bar 82, the bar 82 being pivotally connected to a bracket arm 83 which is attached to a beam 84 on the main frame of the loom. The bar 82' has a pin 85 which projects into a cam groove 86 1n a cam 87 which is sebeing such as to impart an oscillating movement to the shaft 74 after each twisting operation to. cause the knock-off arms 77 to cast the twisted loops from the pins 44. It will be understood'that each strand is beat up by the lay and the warp sheds are changed to tie in the strands of weft so as to weave headings a from which the twisted strands of bullion project in the usual manner of bullion fringe. v

By the use and arrangement of the foregoing structure, we are enabledto produce fringe with uniform twists in the successively made strands of bullion and can accom- ,7d cured to the cam shaft 20, the arrangement.

plish this end without the employment of l delicate springs or other small members which would soon get out of working order and require constant repair and replacement.

Furthermore, we are able to operate all the twister spindles from 'gear wheels on a common shaft which shaft can be positioned as illustrated so` as not to interfere with the roper attention and inspection of the work, urthermore the shafts 26 and 74 can be positioned below the level of the work. Furthermore, the shape of the weft inserting members is such that when in operation one finger can cross a osition previously occupied by a part of tlie adjacent finger when it was in its normal position.

As shown in Figure 2, the bracket 21a is necessary only to supportthe weft inserting member which is required to move loops of thepweft through the adjacent warpy of the fringe G and since there is no warp on the opposite side of said bracket 2la no twister spindle is required. Vice versa the bracket 21b is only required to have a twister spindle to receive the loop of weft *from 'the weft inserting finger on the adjacent bracket finger on the adjacent bracket 21 to twist the strands of the fringe A and therefore the bracket 21b requires no weft inserting member thereon.

In Figure 2 of the drawing the fringes are, for clearness of illustration, shown farther apart than necessary, however it will be noted that they can be positioned much closer together, it being merely necessary to use shorter weft'` inserting members 39 when it is desired to produce the fringes closer together. Furthermore, said close positioning of the fringes is rendered possible due to the fact that there is only one supporting bracket, for a twister spindle and weft inserting member, between each two adjacent fringes. It is therefore cbvious that by having such unitary supports as the bracket 21 between each two fringes the fringes can be positioned very close together in the loom and thatI each of the intermediate brackets 21 form unitary or common supports for parts which co-act with the fringes on each side thereof. For example the bracket 21, which is specifically lettered a, supports the weft inserting member 39 which conveys the weft to produce the bullion of the fringe A and also supports the twister spindle 32 which twists the bullion of the fringe B. Further than this, by providing the bevel gears 30 and 31 a durable drive is provided forthe various weft inserting' members from the well supported shaft 26 which is common to all of the units; the twister operating shaft 37 also being common to all of the units as is also the shaft 74 which effects the knock-off of the bullion from the twister spindles. With our invention therefore we are able to avoid small, weak and numerous parts and at the same time we are able to produce a greater number of uniform fringes simultaneously and economize on space.

In Figures 7, 8 and 9 we have shown a certain modification in the drive for the twister spindles which instead of employing gears similar to the gears 64 and 66 above described, we have illustrated the shaft 56 provided with an ordinary bevel pinion 64 adapted to co-act with teeth 67" on a wheel 66a secured to the cam shaft 20. The teeth 67a only extend partway around the wheel 66a, the surface 68a of said latter wheel being plain and not co-active with the bevel gear 64a. With this construction, in order vto prevent the overrunning of the twister spindles due to inertia after the teeth 67a have acted on the pinion 64, we have illustrated means which will stop the rotation of the shaft 56 immediately after the teeth 67a have passed the teeth of the pinion 64a. Said means consists of a shaft 88 having a detent arm 89 which is adapted at predetermined times to enter a notch 9() in the collar 91 which issecured to the shaft 56. The shaft 88 has an arm 92 which constitutes a follower and engages a. cam 93 on the shaft 20, the follower being held in contact with the cam by a spring 94. The cam 93 is so shaped and timed that when the teeth 67a move out of contact with the teeth of the pinion 64, it will allow the follower to drop from a high point thereof, said movement being assisted by the spring 94. This action will cause the arm 89 to move into engagement with the collar 91 and enter the notch 90 as shown in Figure 9 thereby stopping the shaft 56.

Having .thus described our invention,
